The file 'Fluval 70 Comb 3D Printer Model' is (stl) file type, size is 10.7KB.
This is just a piece I designed to allow me to grow floating plants in my aquarium filter. You could also use it add more media to your filter as well. This fits a Fluval 70 filter. I recommend using a 0.4mm nozzle to print. The teeth in the comb are exactly 0.8mm thick.
